HUB-ATTACHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 278,942, dated June 5, 1883.

vice closed, showing the manner of attaching' a wheel to an axle. Fig. 2 is atop view ofthe same open. Fig. 3 is a longitudinal sectional view of the device. Fig. is across-sectional view ot' the device closed, taken on the line Fig. 5 is a similar view of the direction. Fig. 6 is a section on the line yy of Fig. 4, showing the improved means for locking the device.

Similar letters ot' reference in the several figures denote the same parts.

The object of my invention is to provide a cheap and simple device whereby ay wheel can r be attached to and detached from an axle without the use of a wrench; and to this end it consists in certain novel details of construction and combinations of parts, which I will first describe, and then point out particularly in the claims at the end of this specication.`

In the accompanying drawings, A represents the axle to which the hub is to be attached, provided with the collar. H and the long smooth bearing portion A.

B represents an ordinary axle-box, provided at its inner end with a collar, I, and withy a groove, b, into which a portion, d, ot'the'part of the coupling D and the portion e of the part E of the coupling are adapted to work.

The connecting device or coupling consists of three distinct main parts, C, D, and E. The part C has a projection or extension, c, extending back underneath the axle, to which it is secured by the strap H, which encircles the axle, and has a bolt, Z1, in its under side, adapted to press the projection c firmly against the axle 5 and it is also provided with a groove,

c', in its upper forward portion to receive the collar H ofthe axle A. This part C has a lug, c?, provided with a perforation, through which `passes the pin F, connecting the parts C, D,

and E together. The portion D, which is also pivoted on the' pin F, has a lug, d', through which said pin is passed, and on its opposite end a corresponding lug, not perforated laterally, but having the device G for securing the coupling together, and which will be more fully described hereinafter. This portion D. also has the groove d2, into which the collar I on the box B is adapted to work. Portions C and D constitute the under or lower part of the coupling. The upper portion of the coupling is provided with a bifurcated lug, or, rather, two lugs, ee', perforated and straddling the lugs c'Z and d of the lower portions, C and D. Said upper portion also has grooves e'1 e3 in its inside circumference (the groove et being deeper and wider than c3) for the purpose of retaining the collars on the box and axle, rc spectively. On one end of E are two lugs,

which, when the coupling is closed, embrace the lug on D, containing the devices for locking the coupling together. The locking device on the lug of the portion D is composed of a bolt or stem, K, passing'through a` perforation in said lug, and having a thumb-piece, L, at its upper and a head, M, at its lower end. Between the head M and the under side of the perforation isa spiral spring, N, whose function is to keep the thumb-piece L normally against the top of the perforation.

The operationof the device is as follows: Uien the wheel is to be put on the axle, the

coupling is opened and the wheel slid onto they thumb-piece is then turned across the spaceV between the lugs, and the spring around the stem pulls the stem down, and the thumbpiece, dropping behind the shoulders a a, is prevented from accidentally turning.

The extension c of the part C is only for the purpose of retaining the coupling on the axle and preventing it from rotation, and bears no IOO part of the strain longitudinally of the axle, to which the collars of the axle and hub respectively are subjected.

Having thus described my invention, 1 claim as new--l l. A hub attaching device consisting of three main parts hinged together, and one. of which constitutes one half of the device, and is provided with grooves for the reception of collars on the axle-box and axle, respectively, and the other two of Which together constitute the other half of the device, having grooves or recesses corresponding to those of the firstmentioned part, but which are capable of separation, so as to permit the axle-box, with its -collar, to be slid longitudinally oit' the axle,

one of the parts of the two-part half being adapted to be secured to the axle, substantiallxvr as described.

2. A hub attaching device consisting of three main parts hinged together, and one of which constitutes one half of the device,V and is provided with grooves for the reception of collars on the axle-box and axle, respectively,

and the other two, of which one is adapted to be secured to the axle, together constituting the other half of the device, having grooves or recesses corresponding -to those of the rst- 'mentioned part, but which are capable of sephalf, having the grooves for the reception of the collars on the axle-box and axle, respectively, and the two parts forming the corresponding lower half of the device, one of which is adapted to be secured to the axle, and having grooves for the reception of said collars, in combination with the device for lockingV said parts together, consisting of the thumb-piece, stem, and spring, all arranged substantiallyas described.
